Wards has once again named its ten best engines. Surprise-surprise things are getting smaller. Diesels and four-cylinders are well represented, many a-turbocharger, hybrids, some V6's and only one, lonely V8 engine and that's Korean. Let's take a closer look.

This is the crank for the Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine designed primarily for large container ships. Producing over 100,000 HP, it's the most powerful and efficient diesel engine in the world today.

Until we stumbled upon the NSK booth and saw their automatic transmission from a Lexus LS600h cut-away, we didn't know we'd like checking out hybrid automatic transmissions. We can't believe we're writing this, but... hot tranny porn below. Sigh.

We first told you about the Scuderi Split-Cycle engine's astonishing 140 HP per liter potential back in April when it was just a bench prototype. Now it's running and we've got the exclusive video to prove it. Engine pr0n below.

So how come Corvettes don't come with a cool engine output graph on the engine cover like the HSV/CSV CR8's LS2 engine? See it up-close below.

We've already shown you the Mercedes AMG 6.3-liter V8 engine, the world's most powerful naturally-aspirated eight-cylinder engine, exploded, showing us its bits n' pieces. But we found this testing photo earlier today and frankly, thought it was cool. More below.

Remember the uber-secret Ford "Bobcat" dual-fuel engine — the one that squirts a shot of E85 directly into the cylinder chamber to create diesel-like performance out of a gasoline engine? Thanks to PickupTrucks.com, we've got this exclusive first look!
